[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Suravee Suthikulpanit <Suravee.Suthikulpanit@xxxxxxx>

This patch set introduces support for MSI(-X) in GICv2m specification,
which is implemented in some variation of GIC400.

This depends on and has been tested with the V7 of"Add support for PCI in AArch64"
(https://lkml.org/lkml/2014/3/14/320).

Changes in V3:
    * Rebase to git://git.infradead.org/users/jcooper/linux.git irqchip/gic
      (per Jason Cooper request)
    * Misc fix/clean up per Mark Rutland comments
    * Minor Clean up in the driver/irqchip/irq-gic-v2m.c: alloc_msi_irqs()
    * Patch 4 is new to the series:
        * Add ARM64-specific version arch_setup_msi_irqs() to allow support
          for Multiple MSI.
        * Add support for Multiple MSI for GICv2m.

Suravee Suthikulpanit (4):
  irqchip: gic: Add binding probe for ARM GIC400
  irqchip: gic: Restructuring ARM GIC code
  irqchip: gic: Add supports for ARM GICv2m MSI(-X)
  irqchip: gicv2m: Add support for multiple MSI for ARM64 GICv2m
